4:31 pm
can do attitude. with the price of gold skyrocketing it's tempting to sell pieces in your you'll ri box but how do you get the best price? >> the gold business is booming. byers and sellers and coins and jewelers. how do you get the most money. we asked three gold dealers to check our jewelry and to give us a price. specific precious metals was our standard. they check for quantity and quality and offered $371. >> then our intern went undercover. >> i first went to collectibles and coins in mill valley. >> the gave them the story and e spent a lot of time. he priced it about $371. then we took to a store in san mateo. she said it was 171.
4:32 pm
>> so there is no standard that anyone follows as far as what you have to pay somebody. right? everybody can make up their own price. >> dan of mill valley of precious metals this is not a case of buyer beware but but beware. >> most people really don't know how to calculate how much gold they have. >> how do there is there is a form la to all this. weight times purity times spot times percentage equals price. weight is measured in troy ounces, purity in karats and percentage is how much of the going rate the dealer will pay. to get a ballpark figure get out a kitchen scale, a cheap one is fine and weigh your jewelry in grams. there are 31 grams to a
4:33 pm
these are about half a troy ounce. now look for the sample on the jewelry. 24 carats is nearly 100 gold making 14 karat about these 15%. so this equals..29 and then multi by the spot rate you get $470. shoot for a percentage of 80% leaving 20% for profit and handling and the ballpark price for this jewelry is $375, very close to the 371 offered by two as for west coast gold by others. we asked why the the difference. not knowing the exact details of the transaction, it is difficult to give you an exact answer. one possible reason is the buyer in the store did not evaluate
4:34 pm
properly. we always offer a fair price and back it up with a 110% price match guarantee. >> you really do need to find out the value of the gold, how much you have and how much it's. had i not known was $371 i might have sold it for $171. >> take a few minutes to weigh it and do the math. we have all of this information posted on our website right now at you may be asking yourself, why did all three offers end with $71? there are two explanations, one all three were using similar math formulas and two, it's just coincidence. jeists have bean warning the amount of oxygen is in the ocean is dropping. it's a serious problem that could tlchbt many animals.
4:35 pm
dan ashley reports. >> this is exotic world of the oxygen minimum zone about half a mile deep. the video was shot by the monterey bay aquarium research institute. these animals are especially adapted to live in this habitat. over the last 20 years, that oxygen level has been getting lower. >> everything in the ocean needs to breathe oxygen just like we breathe oxygen in the air. in oxygen goes down, things suffer or die in extreme c willm >> william of stanford university says klit change is definitely happening underwater and many scientists believe it is linked to what is happening above the surface. >> it appears the rate of change is increasing. it's getting more serious as time goes by. >> so scientists and engineers are working together to try to measure the effect of the
4:36 pm
declining oxygen. they are using a remote control vehicle about the size of a vox wal gonl bus. it's guided by the scientists. >> the scientists will sit there let's get that one. >> by just looking at manages thousands of feet deep. this is barrel eye, the holes above eighth mouth is for breathing. the eyes are big green balls behind a transparent shield. the eyes rotate handling go in creatures. >> it keeps the eyes on the food plucks the food from the ten that kals. >> and for the past four years, the team has been developing an instrument to find out how deep sea animals are responding to lower oxygen levels. >> just came back from a week at
4:37 pm
sea. >> they steer the instrument to go into individual chambers. they can live comfortly bli for a day or two while they measure oxygen intake. deep compression happens when they bring them to the surface. it's too early for definitive results but low oxygen is forcing some creature tours find new habitats and their systems are stressed. >> you can certainly see the impact of the declining oxygen on the physiological state of the animals. whether we continue our cheryl jennings takes you on a ride on south korea's high speed rail to see if the effort to build compares to what is happening here. and mother excitement.
